What is an IOSS number & Why an eCommerce Business Should Get One

IOSS stands for Import One-Stop Shop, and it is a system implemented by the European Union (EU) to simplify and streamline the collection, declaration, and payment of Value Added Tax (VAT) on goods imported into the EU by businesses from outside the EU. The IOSS is particularly relevant for eCommerce companies that sell goods to consumers (B2C) in EU member states, and since Brexit this has become an important factor for UK based eCommerce businesses selling into the EU.


Why should an eCommerce Business consider getting an IOSS registration?


VAT Compliance

The IOSS allows businesses to comply with VAT regulations in a more straightforward manner. It simplifies the process of collecting and remitting VAT on goods sold to customers in the EU.


Customer Experience

With IOSS, the VAT is collected at the point of sale, meaning that customers won't face unexpected charges or delays at the time of delivery. This can lead to a better overall customer experience and reduce the likelihood of abandoned carts or customer dissatisfaction.


Faster Customs Clearance

Goods shipped under the IOSS are subject to a simplified customs process, which can result in faster clearance times and quicker delivery to customers.


Competitive Advantage

Offering a smooth and transparent purchasing process, with no surprises in terms of additional charges, can give an eCommerce company a competitive advantage in the EU market.


Legal Compliance

It helps businesses comply with the VAT rules and regulations in the EU, reducing the risk of legal issues and penalties related to non-compliance.


Reduced Administrative Burden

The IOSS simplifies the VAT reporting process for businesses by allowing them to submit a single quarterly return covering all their EU sales, rather than having to register for VAT in each individual EU member state.


To benefit from the IOSS, eCommerce businesses need to register for an IOSS number and ensure that their systems are set up to collect and remit the appropriate VAT at the time of sale. It's essential to stay informed about any updates or changes to IOSS regulations to maintain compliance.
